How to allow user to input as many as numbers separated by commas and then calculate the sum?

Question

The program here restricts user to input 5 numbers followed by consecutive return keys.
I could only declare a variable 'k' to store how many numbers the user wants to enter. But that again doesn't serve the purpose.

int num=1;
int number, k;
int total=0;
cout << "Enter how many numbers you want to add" << endl ;
cin >> k;

while(num<=k)
{
//calculate sum
}

Answer 1

You could add every single input into an array, then use a for loop to iterate over every element and add them to each other.
